IMPROVEMENT IN CORN-PLANTERS.

Specification forming part of Letters Patent No. 130,378, datedAugust13, 1872.

SPEoIFroATIoN.

To all whom it may concern:

Be it known that I, JOHN L. LEAS, of Hampton, in the county of Adams andState of Penn sylvania, have invented certain new and usefulImprovements in Combined Grain-Drill, Corn-Planter, and Fertilizer; andI do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawing andto the letters of reference marked thereon which form a part of thisspecification.

The nature of my invention consists in the construction and arrangementof a combined corn-planter, grain-drill, and fertilizer, as will behereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionapperta'ins to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-A Figure 1 is a perspective view of my machine when used as acorn-planter. Figs. 2 and 3 are similar views of the corn andfertilizer-wheels, respectively. Fig. 4 is a plan view of the grain-box.Fig. 5 is a side view of my machine when used as a grain-drill, and Fig.Gshows a device used in broad-cast sowing.

A represents the frame of my machine. B is the axle, and G G the wheels.Upon one end of the axle B is a common clutch, a, operated by a lever,E, to throw the axle in and out of gear with the wheel at this end. Onthe other end of the axle is a gear-wheel, b, communicating motion to ashaft, d, by-means of a pinion, e, on said shaft. The shaft 61 passesthrough the lower ends of two hopper-shaped corn-boxes,D D, each ofwhich is, by a vertical partition, divided into two compartmentsone forcorn and the other for fertilizer. In the corn-compartment works awheel, G, and in the fertilizer-compartment a wheel, H. The wheel G is,around its circumference, provided with cups 1 l on one side, at equaldistance, while on the other side are cups 2 2, ar-

ranged in groups, as shown in Fig. 2. The wheel H is in like mannerprovided on one side around its circumference with a smaller, and on theother side with a larger, number of cups, 3 3, the object in both casesbeing to deposit more or less of the corn and fertilizer, as desired.The change is effected by means of a bar, f, used in each compartment tocover either half of the wheel, and allow only the other half to beused--that is, the half in thickness or width. The wheels G G and H Hare, of course, firmly secured to the shaft d, so as to revolve with it.In the corn-compartment of each box D is a brush, i, to prevent morethan the desired amount of corn to be dropped. The corn and fertilizerpass through the usual conductor, and plow into the furrow made by saidplow, and are covered by two covering-plows, all of said plows (to eachbox D) being connected to one beam, pivoted at the front end of theframe. 7

When the machine is to be used for graindrill the boxes D D, shaft dwith its wheels, and the beams and plows are removed, and in placethereof the following substituted: I represents the seed-box, extendingthe whole width of the frame, and divided by a longitudinal and verticalpartition into two compartments. In these compartments are placed thetwo rollers h h, connected at one end by gear-wheels or pinions k k, oneof which gears with the wheel b on the axle, and thus contributes motionto the rollers. On the roller h, which is in the seed-compartment, are,at regular intervals, enlargements m m, which are grooved or corrugatedlongitudinally, and as the roller revolves the seed is carried by saidgrooves and dropped through apertures in the bottom of the box.

In like manner the roller h in the fertilizercompartment is providedwith corresponding enlargements a n, which are grooved spirally to carrythe fertilizer out through similar apertures in the bottom of the box.Under the bottom of the box, corresponding with each of the enlargementsm, is a spring, operating in the grooves on the same, to clean the seedout of the same. Under that'part of said bottom corresponding with thefertilizer-compartment are two perforated slides to regulate the size ofthe apertures through which the fertilizer is to pass.

The seed and fertilizer from each corresponding couple of enlargements mand a, pass through one conductor, J, and hoe K, into the ground. Thishoe or plow is attached to a beam, L, which is hinged at the front endof the frame A.

All the hoes may be raised up from the ground at once, or one-half ofthem only, from the center to either end by the following means: At therear end of the frame A are hinged or pivoted two bars, P, extendingfrom the center of the frame to the ends, and to these bars the rearends of the beams L L are connected by chains p 1). Near the inner endof each bar P, to an ear at the lower edge, is pivoted an arm, 0', fromthe outer end of which a spring rod, 8, extends forward and passesthrough suitable guide-loops on the frame. The front ends of these rodsform rings t t, located at such a point that the driver from his seat atM can readily put his foot on either or both of them. To a standard orpost near the front end of the frame is pivoted a lever, It, the lowerend of which is attached to a slide, S, arranged on one of the bars ofthe frame. The rear end of this slide is forked, and each prong forms ahook, or, which hooks, when the lever B is pushed forward, will bedirectly under the rings t t. Now, if the driver desires to raise thehoes or plows on either side of .the machine he puts his foot on thecorresponding ring t, or if all are to be raised, on both rings, so thatby pulling back on the lever either or both of the hooks, as the casemay be, will catch on the ring or rings depressed, and thereby turneither or both of the bars P, raising the hoes.

In like manner either or both of the cornplows may be raised at will.

In sowing broad-cast the conductors, hoes, and beams are removed, and intheir place is substituted a bar, W, with a series of scoops or halffunnels, y y, attachedto it in such a manner as to correspond with theapertures in the bottom of the. box I. The seed and fertilizer fallingon said scoops or half-funnels are scattered in all directions.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters'Patent, is- I 1. The combination with thehopper D, blocks ff, and cylinders H, the parts being constructed andarranged substantially as and
